Abstract

The invention relates to a connecting assembly for connecting a driving device ( 100 ) to a hinged member of a motor vehicle, in particular to a pivotably hinged ventilator window. The driving apparatus adjusts a hinged lever ( 6 ), at the front free end ( 60 ) thereof there is formed an adjustment point ( 61 ), together with a coupling member ( 3 ) which is connectable to the hinged member, and together with a bearing shell ( 4 ), which is positively accommodated in the coupling member ( 3 ) and pivotably supports the adjustment point ( 61 ). To accomplish the necessary motion compensation during the adjustment of the hinged lever and a compensation of tolerances, according to the invention the adjustment point ( 61 ) is pivotably supported in the bearing shell ( 4 ) about an axis (B) perpendicular to the longitudinal axis of the hinged lever and the bearing shell is rotatably received in the coupling member ( 3 ) about its longitudinal axis (A) and perpendicular to the axis (B). By means of this simple assembly, two mutually perpendicular axes can be precisely defined in a simple manner. Overall, according to the present invention the hinged lever can thus be rotated about two mutually perpendicular axes.
